ANTAL Jammer VJ V-GRIP -
Overview

The Antal VJ V-Grip Jammer has a locking V-cam. It offers high
grip, reducing the compression on the line which allows the
line to keep its shape without crushing it. It also reduces
the cover damage and increases the work loads as a result.
The best results have been found on lines constructed of
Dyneema with composite Kevlar/Polyester covers, while traditional
pure-Polyester covers over Dyneema core prove to have poor
resistance. Excellent results have also been found on "all-Polyester"
core/covver versions. There are 3 models of this jammer for
lines ranging from 8 to 18 mm and loads over 5,000 kg. Available
in single and double models. The cam is preloaded using a
winch handle reducing the tension loss. A stop holds the jammer
open to keep the line free. Line
can be tailed with the jammer closed and it will be secured
in the new position automatically.
